It was the world's first such procedure, his doctors say, a risky and experimental trial to fight Batten disease, the brain-wasting illness killing the California boy.
In the four weeks since, his parents say, the 6-year-old has grown more lively each day. The milestones are small: More smiles, more eye contact, more words.

Children lose their ability to see, speak, think and move. They develop seizures and die by their teens. There is no cure.
Some scientists think a treatment lies in neural stem cells, an immature cell that can turn into other kinds of brain cells.

In animal tests, the cells made the enzyme missing in Batten disease..."
